Some of that inflammation can be reversed.
How long does it take lungs to heal from smoking?

In as little as 1 month, a person’s lung function begins to improve. As the lungs heal and lung capacity improves, former smokers may notice less coughing and shortness of breath.
Can you reverse damage from smoking?
Good news! The effects of smoking are actually reversed with every cigarette you don’t have. Over time, your risk of life-threatening health problems, including cancer, reduces dramatically. As soon as you stop smoking your body begins to repair itself.
How long does it take for smoking damage to reverse?
Within two weeks of quitting smoking, you may start to notice you’re not only breathing easier. You’re also walking easier. This is thanks to improved circulation and oxygenation. Your lung function also increases as much as 30 percent about two weeks after stopping smoking, notes the University of Michigan.
Can lung damage be reversed?
Chronic obstructive pulmonary disease makes it increasingly difficult for a person to breathe. It is not currently possible to cure or reverse the condition completely, but a person can reduce its impact by making some treatment and lifestyle changes.
